I finished all three of these games in the arcades (god knows how much money I spent) and have played various verions of them from the terrible C64 version to the too slow to play CD-ROM versions. Here's my thoughts: TL:DR: These are quick-time Disney-esque 80s-style cartoons. Yellow flashes during the scenes indicate what movment or action you need to perform. A flash to the left of the screen means you should hit left. A flash on your sword means you should use the action button. Timing on the quicktime input is razor thin leading to a lot of dying and having to start over from the begining. Finishing the games requires a lot of trial and error and memorization. That said the games are a lot of fun to watch with great characters, animation, sound and music. Dragons Lair: Game started the laser disc game craze in the 80s. This looked like unlike anything at the time. So was the 50 cent or $1 cost per play. You guide Dirk the Daring through a castle to rescue the princess Daphane. The game is broken up in to small scenes leading up to the confrontation with the dragon. You do get a sense of accomplishment completing some of the longer sequences and of course completing the game. Space Ace: My favorite of the bunch. You play Dexter who at certain times during the game can turn in to ass kicker Space Ace. The scenes play in order so the game plays out more like a movie. The improvement they made was that you have some minor additonal choices. You don't always have to turn in to Space Ace right away. If you don't scenes will extend a bit more or play out differently. The ending to this one is also my favorite. Dragons Lair II: Similar to Space Ace in that scenes play in order but there is no additonal choices. In order to compete the game you do have to spot and grab objects during your playthrough. Scenes are a lot longer in this game. If you die you have start again. The game is more difficult to complete. But worth it. My second favorite of the bunch,
